Further Information
This paper deals with solutions to overcome or to correct for the defects of photon-counting detector ― intensified CCD (ICCD) in particular ― for the purpose of speckle interferometry. Among others, we show how to cope with strong image distortion in the photon-counting case and with the so called photon-counting hole. The latter is due to the incapacity to detect any pair of close photon-events in the short exposure images. Our photon-counting detector, the CP40 camera (Blazit 1987; Foy 1988a), consists in an ICCD and centroiding electronics. Nevertheless, other photon-counting detectors present a defect similar to the photon-counting hole due to the limited shortest time delay between two consecutive photon-events.
